VAG-INAL S'YRINGE.

Specification of Letters Patent.

Application led June 16, 1911.

T0 all whom t may concern:

Be it known that we, SVEN S. RUMBERG and FELIX C. HARTTUNG, citizens of the United States, and residents of the cities of Batavia and Chicago, counties of Kane and Cook, respectively, and State of Illinois, have invented certain new and useful Improvements in Vaginal Syringes, of which the following is a specification.

Our invent-ion relates to improvements in vaginal syringes and has for its object the provisio-n of a syringe of this character which shall be efficient in operation and convenient in use.

Our invention consists in the combinations and arrangements of parts hereinafter described and claimed.

Our invention will be best understood by reference to the accompanying drawings forming a. part of this specification and in which,

Figure 1 is a sect-ional elevation of a syringe embodying our invention, Fig. 2- is a detail bottom plan View of a valve employed in the syringe, Fig. 3 is an end elevation of a vent plug, Fig. 4 is a sectional elevation showing a modified form of syringe, and Fig. 5 is a vertical section of a pump used in connection with said modilied form.

The preferred form of construction as illustrated in the accompanying drawings comprises a cylindrical body portion 1 having a reduced end 2 on which is secured a soft rubber neck 3, the body being preferably of hard rubber. To prevent too rapid radiation of heat through the reduced end 2 and neck 3 a protection lining 4 is provided which substantially conforms to the shape of said reduced portion as clearly illustrated in Fig. 1. Screwed into the body 1 at one end thereof is a plug 5 having a shoulder 6 fitting the end surface of said body and forming a water-tight joint therewith. The interior of the plug 5 is internally threaded at the center thereof for the reception of the threaded end 7 of an axially disposed tube 8 which is smaller than the opening of the neck 3 as clearly shown. The tube 8 passes through the opening of the neck 3 and terminates in a. nozzle 9 of rounded form. In this manner an annular passage is formed for the return of fluid into the body 1 as'indicated by arrows in Fig. 1. A check-valve 10 having a stem 11 is provided in the nozzle 9,

and to limit the movement of said checkvalve a pin 12 is passed through an aperture 13 formed in the stem 11. Fluid is discharged through the nozzle 9 as indicated by arrows, the check-valve 10 automatically closing to prevent return flow of said fluid. Registering with the tube 8 is a passage-way 14 which is inclined to said tube and in open communication with the rubber bulb 15 by means of which fluid conta-ined therein is forced through said passage-way, and tube to the dischargenozzle 9. Inserted in the bulb 15 is an internally threaded nipple 16 which is readily screwed onto or off from a threaded boss 17 disposed axially on the exterior end of the plug 5. A locking nut or washer 18 is provided for effecting a tight connection between the nipple 16 and boss 17. As aforesaid fluid returns to the interior of the body 1 through the annular opening formed between neck 3 and tube 8, and in order that said fluid may return to the bulb I5 an inclined passage-way 19 adjacent the passageway 14 is provided in t-he plug 5, there being a check-valve 20 to prevent outflow ofV fluid from the bulb 15. Check-valve 20 is adapted to seaton a conical seat 21 and is provided with a substantially rectangular stem 22 as shown in detail in Fig. 2. A diametric pin 23 is provided adjacent the check-valve 20 to limit t-he movement thereof as clearly shown in Fig. 1. A plug 24 is screwed into one side of the body 1, and into the other side is screwed a vent nipple 25 having an axial passage 2G and a radial passage 27 leading from the axial passage to atmosphere. A bore disposed in axial alinement with the passage 26 is formed in the nipple 25, therebeing a conical valve seat 29 at the juncture of said bore and passage. Diamet-rically opposite perforations 30 are provided to establish communication between the bore 28 and the space between the lining 4 and wall of the body 1 in order that air contained within said body may pass freely to atmosphere in advance of the return flowing of fluid into said body. A ball 31 limited in movement by a diametric pin 32 is seated on the conical valve seat 29 by means of the impact of the rush of fluid toward the nipple 25 after the air has escaped or partially escaped from the body 1. Thus leakage of fluid is prevented. It is apparent that when the device is held in the proper position during the operation thereof that air will escape freely through the vent without moving the ball 31, but not so with the water or other fluid contained in the body l since the inertia of the ball ,is not sufficient to withstand the impact of the heavy liquid without seating on the seat provided therefor.

The syringe as described in th-e foregoing is particularly efficient for maintaining a circulation of fiuid from the bulb, out through the discharge nozzle, and thence back to the bulb past the return check-valve, the fiuid in this manner being used over and. over again. But if it is desired to have a continuous flow of water or other liquid, the bulb is omitted and the syringe modified to be used in connection with a water faucet, hot water bag, or a pump as will be presently described.

The modified form of syringe as shown in Fig. 4 is similar in all respects to the preferred form except that instead of the plug 24 a nipple 33 is used. Also a coupling 34 is substituted for the nipple 16 of the preferred form. A water faucet, not shown,

may be connected with the coupling 34, or

a hot-water bag 35 may be connected therewith by means of a flexible hose 36. Y A pump comprising a cylinder, plunger 38, operating handle 39, return spring 40, and check-valves 41 and 42 may also beconnected with the coupling 34 if it is desired to have an efficient self-contained outfit. In the operation of the modified form of syl.- inge the fluid is continuously discharged through the nozzle 9, whence the same flows back through the annular passage into the body, and then to a suitable receptacle through the flexible hose 43.

Syringes of the construction and design set forth are simple of construction and eiicient in operation.

While we have illustrated and described the preferred form of construction for carrying our invention into eect, this is capable of variation and modification without depart-ing from the spirit of our invention. We therefore do not wish to be limited to the precise details of construction set forth, but desire to avail ourselves of such variations and -modifications as come within the scope of the' appended claims.

Having described our invention what we claim as new and desire to secure by Letters Patent is:
